1. A small amount of sediment at the bottom of the tank shouldn't be an issue. The best way to to remove this is to get a thin piece of pipe (like aquarium air tube) and create a siphon then suck it out of the tank into a bucket.

2. Live baby brine shrimp is the best food for some species of jellyfish, yes. Most of the jellies that eat fine plankton in the wild do well from LBBS but other species eat everything from live fish to other jellies.

3. One of the easiest jellies to feed are moon jellies, they grow quickly when fed either LBBS or the powder food that we produce. There are lots of other species that are recently becoming available and are hardier than moons in a lot of ways but some of them are trickier to feed.

Flame jellies do well in aquariums but will need to be fed some LBBS because they don't do as well on a diet of 100% powder food.

Blue Blubber jellies are very hardy when it comes to water quality, temperature and even salinity swings but we haven't found a good food which sustains them past 4-6 months yet. We are currently experimenting with different types of zooplankton. LBBS seems to be one of the best for blubbers at this point but we still aren't getting the life expectancy we would like to see

Spotted Lagoon Jellies do well in aquariums but need high power lighting because they are photosynthetic.

Just to be clear are you talking about an Orbit 20, Pulse 80 or Pulse 160? The Orbit and Pulse 80 are both in their second generation.

The pumps on all of our tanks should be almost silent. If its making any noise then you should disconnect it from the power/pipe work, pop off the front cover and slide out the impeller. Give it a rinse under a tap and make sure there is no grit or anything else stuck inside. Be careful you don't lose the little plastic end caps on either side of the impeller. Put it back together and see if this solves the problem.

If after doing this the pump is still noisy then drop us an email with your purchase information and address. We will look into getting you a new pump sent out.
